Variety description

10 August 2026

The variety belongs to hexaploid soft wheats and serves as a reference sample for evaluating the hairiness of the apical segment of the ear rachis. Historically, the variety has served as an object for studying the genetics of yellow rust resistance.

In scientific research, the variety is known for its technological grain characteristics, including gluten aggregation capacity and the content of alpha-amylase trypsin inhibitors. Due to its properties, it is often used in breeding as a comparison object in genetic research.
